Hi,
which file to use for the BCM43241 chip? It is not listed in your devices file.
I need it for my Sony SVD1321c5e

Hello.
This is different kind of Broadcom devices, previous generation of their BT stack, based on UART architecture (not USB). So, there another kind of drivers. Luckily Broadcom shipped *.hcd as is in package, and you don't even need to convert them.

Here your driver package (well, one of them) - http://www.catalog.update.microsoft.com/Search.aspx?q=Broadcom%20-%20Bluetooth%20Controller%20Non%20USB%20-%20Broadcom%20Serial%20Bus%20Driver%20over%20UART%20Bus%20Enumerator

So you need correct hdc. For that I need some info from your system. Please, post outputs from these commands:

dmesg | grep -i Bluetooth
lspci -nnv

your link does not work for me.

Ah, this is UART device, they not showing in lspci. Please post udevadm info -e output.

And since this is Broadcom combined device, you may also need to initialize WiFi subsystem first as described in [1][2]. Make sure that you have at least Linux kernel 3.13 and latest linux-firmware package installed.

I already added the brcmfmac43241b4-sdio.txt as described in 1 and 2.
The kernel is 4.1.

The udevadm info -e output is in the attached file
udevadm.txt

OK, your device is BCM2E47 and you need BCM4324B3_002.004.006.0130.0132.hcd file from Broadcom UART driver pack (here is latest from Windows Update - http://download.windowsupdate.com/d/msdownload/update/driver/drvs/2017/10/x86_d7769b81511890a89db78a0384c288222871164c.cab).
Still, I don't know how to enable bluetooth stack on UART since I don't have one. Can you try this guide https://wiki.debian.org/InstallingDebianOn/Thinkpad/Tablet8#Bluetooth ?
After all operations please post dmesg whole output.

After following the instructions the bluetooth chip is recognised, but its connections are really unstable.
Though it is not possible to use it for my mouse, it does not connect, or for BT speakers, which are lagging.
To connect BT i have to run btattach --bredr /dev/ttyS4 -P bcm & after every startup.

The output of dmesg is in the attatched file.
dmesg.txt

Yes, I see initialization. Now your system asks firmware "brcm/BCM4324B3.hcd". Copy BCM4324B3_002.004.006.0130.0132.hcd from CAB-file to /lib/firmware/brcm/BCM4324B3.hcd and reboot (or even turn off/turn on). After that run btattach and bluetooth should run correctly.

Now after btattach --bredr /dev/ttyS4 -P bcm & it stucks while scanning for devices, making it impossible to connect.

The output of new dmesg is attached again.

Well, here my knowledge ends. I see that firmware was successfully loaded (BCM (002.004.006) build 0132), but after that it hangs. I suspect that kernel not fully supports this device. Try to ask on Bluetooth-next mail list ([email protected]), maybe people there can help.

Hi,
this issue is some years old, but i just got a Lenovo Yoga Tablet 2-1051F which uses the same wifi+bluetooth chip. I installed Fedora and pretty much everything worked except the bluetooth keyboard.
I searched around some and found this issue here as well as this blog post: https://daduke.org/linux/yoga.html
I tried installing this package from rpmfusion first, but i didn't check the supported devices list, and to no surprise it didn't work. So i unistalled broadcom-bt-firmware again and did it the manual way:

The BCM4324B3_002.004.006.0130.0161.hcd downloadable from the blog and the one in the Cab-archive from microsoft seem to be the same. Also i guess the last digits of the filename is some version number, so the 0161 is the latest i could find.
I only had to copy the file to /lib/firmware/brcm/BCM4324B3.hcd, made a restart and it worked fine.
i didn't use btattach or anything else.

I don't have much experience with Linux driver stuff, i just wanted to share my experience and what worked for me.
I hope this help someone with some old device.

@Thorbijoern please open new issue with info needed to investigate your case.

@winterheart there is no further issue and nothing to investigate here i think, i just wanted to share my findings...
i had the same problem with the same chip, thats all
